Ohio officials probe possible swine flu cases

Ohio health and agriculture officials said Wednesday they are investigating the cases of 10 sick people whose illnesses have similarities to a swine flu virus. All had attended the same county fair, and officials at the big Ohio State Fair were stepping up precautions.

State and Butler County health departments say preliminary laboratory tests indicate possible H3N2 variant flu virus, which can be contracted by humans from being around infected hogs. Officials say all 10 had contact with hogs at the Butler County Fair, which ended last weekend in Hamilton, in southwest Ohio.
